We're dividing 939910 by 28 
The aim is to understand the frequency of 28 in 939910.

Moving on to step 1:
9 divided by 28 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 28

Moving on to step 2:
93 divided by 28 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 84 away from 93, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 28

Step 3:
When dividing 99 by 28, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 15 after subtracting 84 from 99.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 28

On to step 4:
28 can be fit into 159 5 times, resulting in a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 335.0
Deduct 140 from 159 and we're left with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 28

Going ahead to step 5:
28 can be fit into 191 6 times, resulting in a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 3356.0
If we take 168 away from 191, we end up with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 28

Moving on to step 6:
28 goes into 230 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 33568.0
Subtract 224 from 230 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 28 fits into 60 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 33568.2
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 33568.21
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 33568.214
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 33568.2142
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 33568.21428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 33568.214285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 33568.2142857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 33568.21428571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 33568.21428571, with a leftover of 1.2e-08.
